ln theacoompanyiug drawings, Figure `1 represents a longitudinal central section of the nozzle adjusted to throwsl small stream.; Fig.

' 2*, e similar sectionV with the parts adjusted to throw slargo str. Figrepresents the nozzle as adapted to throw e 'spray or series of nue jets. l

A tube, A, isl provided at one end with a screw-thread, a, by which to attach 'it to a pipe, through which the duid passes, orto'the end of 'the .hose in suitable manner. Around this supply-tube dts a casing or shell, B pro widen. intel-nelly nini e stresser, l which it is adjnstably secured to the tube by *means ol a corresponding screw, b1, cut there -on -Nr its upper or outer end the easing Bv is internally shouldered at' b, and above this annular shoulder the-casing is provided with a series of perforation's extending around lt in rows of any desir. number. The tube Y A tssnngly in the shell or easing B, the outer diameter of the tube, about corresponding with :the inner dia'njlefuar` of the shell at or nearthe ends-ot "the latter, as shown. The upper or 'outer end of the tube A informed or provided with arms or branches, forming a cage sup. porting or terminating in a screw or threaded atud,.ll., The stud t) has a shonlderf'p, and beneath this shoulder is made inclined, so as to dually deect the water impnging against It.. A detachable nozzle, D, for throwing a small stream, screws onto' the end of the tube A upon "the stnd O, the lower orinnerend of the nozzlebeiug .provided-with an annular flange, d," between which and the shoulder c a washer of leather or other suitable material is clamped to maken tight joint. The nozzle D tapers' gradually upward from the flange d iby' ' for a short distance, and is'then formed with an abruptly-inclined or tapered annnlarshoulder, D', between which and the shoulder d side openings dd' are made in the nozzle. Above 4 the upper shoulder Dl the nozzle tapers toward its outer end, as shown. A detachable -outer casing or cap, E, having a. nozzle, E', is se-` cured upon the' shell or tube-casing B by means of threads respectively out -upon the outside of the casing B above its shoulder B', and upon the inside of the end of the cap or outer casf ing. `'lhe inside diameter of the body of the casing E is considerably larger than the largest portion ofthe inner nozzle D, as shown, and forms a chamber or water-wsy,-F, into which the water issues from the tubeA. This chamber contracts at the or discharge end, which isof a somewhat con cal form, and communicates with and terminates' in the way or passage'ot the nozzle portiouE of the cap. A wast-aunt', G, for preventing leakage by water passing down between the inlet or supply tube A'and shell B, screws ontoV the lower end of theshell and ts over the tube, as shown.`

l Instead of the tube A, shown as adapted to bescrewed onto the end of a hose-pipe, it is obvious that the end of the pipe may be formed like the tube to adapt it to receive the nozzle D and cap and nozzle EE; but I prefer. the

.construction shown, as it enables ine-to apply .my improvements tothe branch pipes of hose already iu use. y

'In operation, if a small stream of wateris to 'be used, the tube A is adjusted, by screwing it up, to bring the conical or tapering shoulder D of the nozzle D against the inner walls f of the cap E at the'top of the chamber F,

around the large noz'zleway, thus closing communicatioubetween the water-chamber and large nozzle. When thus adjusted the duid 4enters the chamber 'through the end ot: the

t-nbe A, between its branches, beneath the valve formed by the washer and shoulders c andd. The inclined lower portion of the stud() dei fleets the water outward and upward, while the formation of the flange d on the' nozzle is such as to offer the least resistance to the passage of the water to the openings d' d', through which it escapes in `a stream at the en d of the nozzle. When a large stream is to be thrown thi. parts are adjusted as shown in Fig, 2, when the Water passes, by the chamber F, throughthe two nozzles D E', issuing at the en d of the nozzle E (which should be slightly contracted at its end to compensate for the space occupied by the shorter inner nozzle) in a solid:

stream. When a large' stream'is tobe used the nozzle D may be entirely removed, i( delIt is obvious that vertical jet-openin gs may be made in the shoulder d, to produce a more eiicient spray for .sprinkling gardens ,.&c.,

1., The combination, substantially as hereinbefore set forth, of`the supply-tube and the nozzles of-diierent sizes, adjustable relatively to each other, as set forth, whereby streams oi'dii'erent'sizes may be thrown lfrom a common supply-tube.

2. The combination of the supply-tube, the,

shell or casing adjustabyly secured thereto, the

chamberetl'outer casingor cap provided with a. nozzle, and the inner nozzle, the .water-way,

or passageof which communicates with the chamber in the outer casing, substantially as and forthe purpose set forth. o

- The combination, substantially as hereinbefore set forth, of the supply-tube, the shell or casing adj ustobly secured thereto, and provided with jet-openings at its outer'c`nd',-"a i'1dl the valve ou the end of the supply-tube, for the purpose specified. 4. lThe hose-nozzle hereinbefore set forth,

vconsisting of a supply-tube, a shell or casing adjustable thereon, nd provided with a.' series ot' perforations 'at its outer end,I a nozzle detachably secured to the supply-tube, andl anouter casing or cap providedl with a nozzle,

and detachably secured to thev inner shell or casing', these parts being constructed and operating substantially as hereiubefore set forth,

to adapt the nozzle to throw' solid streams of di''erent sizes, or a`spray. d
